Pollen Index: 9.7 Pollen Level: high Predominant Pollen: Oak, Birch and Grass. The pollen levels for Sunday will be falling in the moderate range. This change results in part from falling temperatures, rising humidity, and heavy rains in the afternoon which tend to wash pollen out of the air. This will improve your outlook if you have allergies and enjoy the out of doors.
